Why We Don't Make Nickel-Free Cookware

Lately we’ve gotten a steady stream of messages from cooks who’ve seen a video warning them to throw out their 18/10 stainless steel and switch to “nickel-free” cookware before it leaches dangerous metals into their dinner. It’s a fair thing to wonder about, and we’d rather answer it honestly than wave it away.

So here’s our honest answer: the nickel scare is mostly overblown, “nickel-free” cookware solves a problem that barely exists by introducing a real one, and — counterintuitive as it sounds — the higher-nickel alloy we use is actually the better choice on the very dimension the scare is about. Let’s walk through why.

What nickel is actually doing in your pan

It helps to start with what nickel is even there for, because it isn’t a contaminant that snuck in — it’s a deliberate ingredient. Stainless steel resists rust because its chromium forms a thin, self-healing oxide layer on the surface. Nickel’s job is to make that protection more stable and more durable, which is why nickel-bearing grades hold up so much better against the acidic, salty conditions that cooking throws at them.

That matters because corrosion resistance and metal leaching are two sides of the same coin: the better a steel resists corrosion, the more tightly it holds its own metals — nickel included. We go deeper on the metallurgy in Metallurgy 101, but that’s the key idea to carry into the health question.

Does stainless steel leach nickel? Honestly — a little, sometimes.

We’re not going to tell you the number is zero, because it isn’t. Stainless steel does release tiny amounts of nickel and chromium into food, and a few conditions push that higher: a brand-new pan, long simmers, and acidic ingredients like tomato sauce. Research on the worst case — a new pan cooking acidic sauce for hours — has measured nickel in the tens of micrograms per serving.

Two things keep that in perspective. First, it drops off sharply: leaching is highest when a pan is brand new and falls as the protective oxide layer matures over the first several uses. Second, those micrograms are tiny next to what’s already on your plate — which is the part the scary videos leave out. (We compare leaching across cookware types in Metal Leaching.)

Your dinner already has more nickel than your pan

Nickel isn’t exotic. It’s in soil and water, which means it’s in food — concentrated in exactly the foods people think of as healthy: oats, nuts, legumes, whole grains, and chocolate. A typical diet runs a few hundred micrograms of nickel a day, and a single wholesome bowl of oatmeal with nuts can carry more nickel than a worst-case acidic simmer pulls from a pan.

On top of that, your body absorbs less than 10% of the nickel you eat and clears most of the rest. For the general population, there’s no evidence that dietary nickel — whether from food or from cookware — causes harm. The pan is a rounding error next to breakfast.

So why not just make a nickel-free pan for the people who want one?

Because “nickel-free” almost always means 18/0 — a ferritic stainless steel with the nickel stripped out — and that’s a genuine downgrade, not an upgrade. Without nickel, 18/0 is among the least corrosion-resistant stainless steels: it dulls, it’s more prone to rust, and it gives up performance over a lifetime of use. (It’s the grade most cookware reserves for the exterior, where induction compatibility matters and food never touches it.)

Here’s the part that ties it together: because leaching tracks corrosion resistance, a lower-grade nickel-free pan doesn’t reliably win the leaching argument it’s sold on — it just trades a trace of nickel for worse durability and more iron. Putting a “healthier” label on a worse pan isn’t something we’re willing to do.

It’s the same reasoning that sends our cookware in the opposite direction. Our Titanium Series uses 316Ti, which actually contains more nickel than standard 18/10 — but pairs it with added molybdenum and titanium for substantially better corrosion resistance. Better corrosion resistance means the metal stays locked in the steel, which is why this family of alloys is often recommended even for people who are cautious about nickel. More nickel, less leaching: the opposite of what the marketing would have you guess.

If you actually have a nickel allergy

One honest exception. A small share of people — on the order of 1% — have a true systemic nickel sensitivity that can react at dietary levels. If that’s you, the most effective lever by far is your diet, not your cookware, since that’s where the overwhelming majority of your nickel intake comes from — and it’s worth a conversation with your doctor.

On the cookware side, the practical steps are simple: break in a new pan over a few uses before leaning on it for acidic dishes, and don’t leave a long tomato simmer going in one that’s brand new. A corrosion-resistant surface like 316Ti is among the better stainless choices here, for the same reason it resists leaching generally.

Our bottom line

We could make a nickel-free pan. It would be easy, and we could put a “healthier” sticker on it. We don’t, because it would be a worse pan sold on a premise the science doesn’t support. We’d rather build cookware that performs and lasts a lifetime — and give you the honest version of the story, nuances and all.
